BACKGROUND

Water conservation is a concern for numerous economic and environmental reasons. Dual flush technology provides operators with a “low volume” flush option (usually about 2 to about 4.5 liters) and a “high volume” flush option (usually about 4 to about 9 liters). The option selected depends on the contents of the toilet bowl after use, with the flush disposal of liquid waste requiring only use of a “low volume” option while a “high volume” option could be used for solid waste disposal. However, a dual flush toilet limits the selection of volumes to two discrete amounts, “low” and “high” flush volumes. Further, a dual flush toilet leaves the selection of the volume to the discretion of the operator, who may choose a “high” flush volume when a “low” flush volume otherwise would suffice.

Furthermore, when a toilet malfunctions, such as when there is a clog, constant flush condition, and/or failure of a toilet component, water may continually run into the bowl or may not exit the bowl. This may all lead to wasting of water, resources, money, and/or damage to the toilet, bathroom and/or building. Therefore, a need exists for sanitaryware which may determine the contents of the toilet and flush the appropriate water level. A need further exists for sanitaryware which may communicate with other devices to operate in a manner that controls water flow through a device. A further need exists for connected sanitaryware systems and methods. A further need exists for connected sanitaryware having improved sensing and wireless communication.

A plate may conceal and/or be associated with or coupled to a flush valve assembly comprising an electromechanical flush valve, water inlet, water outlet, antenna, antenna lens, presence sensor, presence sensor lens, manual override actuator, controller, or battery. In some embodiments, a plate may comprise zinc or stainless steel.

In some embodiments, a flush valve assembly may be powered by a battery. In other embodiments, a flush valve assembly may be powered by a building electric supply or both.

In some embodiments, a flush valve may be an electromechanically operated valve. In some embodiments, a flush valve may comprise a solenoid valve. A flush valve assembly may comprise a water inlet in fluid communication with a water source. A flush valve assembly may comprise a water outlet fluidly coupled to a sanitaryware fixture. In some embodiments, a flush valve assembly may comprise an angle stop.

In some embodiments, an electromechanical valve, a sensor assembly, a presence sensor, a controller, and a power source (e.g. a battery) are all in electrical communication and electrically coupled.

An ultrasonic sensor may be a piezo ultrasonic transducer, for example a piezo-ceramic transducer. A flush valve assembly comprises a presence sensor associated with a presence sensor lens. In some embodiments, a presence sensor may be an infrared (IR) sensor. A flush valve assembly comprises an antenna configured to communicate with a network gateway. A flush valve assembly comprises a manual override actuator, which may be a push-button, lever, switch, and the like.

In some embodiments, a network gateway is configured to communicate with a cloud/server and/or with a computing device via a cloud /server. Computing devices may include smartphones, laptop computers, etc. A flush valve assembly comprises a controller (microcontroller). A controller may be in electrical (wired) communication with a status sensor, a presence sensor, and an antenna. An antenna is in wireless (e.g. BLUETOOTH) communication with a network gateway and/or an internet-connected device such as a smartphone, laptop, other sanitaryware, other computing devices, and the like.

In some embodiments, an exposed flush valve upper housing may be coupled to an antenna lens, wherein an antenna is positioned below the lens. An antenna may sit on and be coupled to a controller. In some embodiments, an exposed flush valve upper housing may comprise a cap, wherein the cap is the antenna lens. In some embodiments, a concealed flush valve assembly plate may comprise an aperture comprising an antenna lens. In some embodiments, a plate aperture may be a horizontal slot, for example a substantially rectangular-shaped, horizontally-aligned opening. In some embodiments, a concealed flush valve assembly may comprise an antenna box, wherein an open end of the box is coupled to an antenna and the antenna is positioned behind an antenna lens.

In some embodiments, an ultrasonic sensor may be coupled to an interior or an exterior of a bowl to receive liquid or solid waste. An ultrasonic sensor may be configured to emit ultrasonic signals through water contained in a bowl, and receive ultrasonic signals reflected back. In some instances, ultrasonic signals are reflected back to a sensor from an unobstructed water surface (water seal surface). A water surface obstructed by solids may scatter or absorb signals, such that they are not reflected back to a sensor. A controller, having collected the information from an ultrasonic sensor, may determine a time-of-flight (ToF) of the signal or signals. A controller may compare a measured ToF to a standard ToF to determine bowl contents (bowl status), liquid or solid. Accordingly, a controller may then instruct a flush valve to initiate a low volume flush or a high volume flush.

In some embodiments, a status sensor may be in a “sleep” mode, that is, not emitting or receiving signals and/or communicating the signals to a controller. Upon a presence sensor determining that a user is present, a controller may instruct a status sensor to “wake up” and transmit and receive signals and relay the information to a controller. In some embodiments, a sleep mode may include periodic (regular or irregular intervals) “waking”, where a sensor will emit and receive signals to check for proper water seal level and/or object/solids presence. For instance, a case of infrequent use, if it is determined that a water seal has partially or completely evaporated, a controller may instruct initiation of one or more flush cycles to re-fill the bowl.

In some embodiments, an assembly may comprise or more flow sensors or flow rate sensors for detecting a flow of fluid through an angle stop, through a flush valve, or through the sanitaryware, etc. In some embodiments, an assembly may comprise one or more pressure sensors for detecting water pressure at one or more locations within the sanitaryware, valves, or plumbing lines.

A controller may comprise a timer or clock, such that a controller may determine a length of time a user is present at a sanitaryware fixture. A length of time may be associated with liquid or solid waste. In some embodiments, a bowl status determination based on ToF may be confirmed with a determination made with a timer. In some embodiments, without confirmation, only a low volume flush will be performed. “Without confirmation” may mean if a timer determines one of liquid or solid waste and an ultrasonic sensor determines the other of liquid or solid waste. If required, a manual override actuator may be employed to provide a further flush. In some embodiments, a manual override actuator may provide a feature to initiate a low volume flush or a high volume flush. In other embodiments, without confirmation, a controller may employ data from a timer or an ultrasonic sensor as a default over the other in regard to determining a bowl status.

In some embodiments, an ultrasonic sensor may be placed on a sanitaryware bowl underside, in some embodiments, directly beneath and substantially centered relative to a water seal. In some embodiments, with a toilet bowl having a trapway inlet and jet outlet in a sump area, an ultrasonic sensor may be positioned on a bowl underside and substantially centered between a trapway inlet and jet outlet in x-y directions.

In some embodiments, a method of coupling an ultrasonic sensor to a bowl may include machining a bowl surface to remove a glaze. In some embodiments, an adhesive, comprising one or more different adhesives, may be employed to affix an ultrasonic sensor to a sanitaryware device. In some embodiments, a sanitaryware fixture may include a pocket or recess configured to receive an ultrasonic sensor. A thickness of a sanitaryware fixture may be somewhat thinner in a recess area to facilitate ultrasonic signal transmission. In some embodiments, an adhesive includes a 2-part methylmethacrylate adhesive. In other embodiments, an adhesive includes an alkylcyanoacrylate ester adhesive. In certain embodiments, certain parts of an ultrasonic sensor are affixed with a 2-part methylmethacrylate adhesive, and other distinct parts are affixed with an alkylcyanoacrylate ester adhesive. In some embodiments, an ultrasonic sensor is electrically coupled to a controller via a wire, wherein the wire runs from underneath a bowl and directly behind a wall to a concealed assembly, or from underneath a bowl and directly on a rear side of an exposed flush valve assembly through a wire cover or housing positioned on a water outlet pipe.

In some embodiments, a sanitaryware status may include a normal state or an abnormal state. An abnormal state may include a clog state, a leak state, a slow-drain state, etc. A sanitaryware may communicate its status to a network gateway via a flush valve assembly antenna. Upon determination of an abnormal state, a controller may be configured to not send any flush signals to a flush valve, and to inform a technician via an internet-connected device. In some embodiments, upon determination of an abnormal state, a controller may be configured to send a signal to close an angle stop. A sanitaryware fixture may be part of a connected system, comprising a plurality of sanitaryware fixtures.
